 Existing mechanical systems were inefficient and reaching
the end of their serviceable lives
 Poorly designed, difficult to maintain lighting
 Inadequate ventilation
 Inefficient use of Market floor

8. Stand Holder Needs
 Access to electrical and plumbing systems was not
available at each stand
 Electrical system was unreliable. Billing for electric
use was by an inequitable formula.
 Congested aisles discouraged visitors at peak times
 Outdated, difficult to maintain stands

9. Project Goals
 Rehabilitate deteriorated historic materials
 Restore original configurations where feasible
 Accommodate universal accessibility
 Increase rentable space on Market floor
 Upgrade building infrastructure
 Improve visitor experience
 Provide public restrooms
 Provide all stand holders with access to reliable utilities
 Encourage energy efficiency of stand holder equipment
 Restore building within limitations of current building code requirements

10. Project Funding
 Redevelopment Capital Assistance Program Grant
 Save America’s Treasures Grant
 Local public funds from the City of Lancaster and Lancaster County
 CMT private fundraising Campaign

11. Project Overview and Scope of Work
 Masonry rehabilitation
 Window and door rehabilitation
 Mechanical, plumbing and electrical
system replacement

 Elevator installation
 Restroom and mezzanine replacement
 Lighting replacement
 Sprinkler system installation

12. Design Concepts
 Conformance with the Secretary of the Interior
Standards for Rehabilitation of Historic
Structures
 All new elements should blend with the original
materials and design features
 Restore use of floor space for market stands

13. Interior Lighting
 Over 500 incandescent lamps removed
 40 high efficiency metal halide pendant
downlights installed
 Minimal accent uplighting highlights
building structure
 Surface mounted exterior lighting will be
removed as part of 2012 streetscape
project

14. Masonry Rehabilitation
 Custom blended hand made bricks
 Laboratory testing of historic mortars and
bricks
 Over 16,000 bricks replaced
 Building fully repointed on three faces to
remove inappropriate mortar installed in
the 1970’s

15. Masonry Rehabilitation
 Selective repairs to rusticated brownstone masonry

18. Concrete Slab Trenching and Rehabilitation
 Existing concrete slab was laboratory tested to determine
composition
 Custom blended concrete and aggregate to match existing
slab
 New concrete was ground to expose aggregate and match
adjacent, historic concrete

19. Basement Excavation
 Creation of a basement required
excavation below the existing south west
tower
 Extensive rock removal within the
building required a variety of techniques

20. Market Stand Modification
 Numerous original market stands still in
use
 Design prototypes developed based on
historic stands
 Existing canopies reduced to comply
with sprinkler code requirements
 Aisles widened to approximate original
aisle

21. Systems Replacement
 System replacement to update systems currently at
the end of their serviceable lives, including:
 Electrical service and distribution system
 Fire alarm and detection system
 Plumbing systems
 Heating and ventilating systems
 Sprinkler System was added for protection of the
irreplaceable historic building
 Existing restrooms were replaced with universally
accessible restrooms

22. Mechanical System Design Concepts
 New systems are located to restore usable space
to the Market floor where possible
 Systems are designed to blend with the historic
character of the building

23. Electrical System Replacement
 Removal of electrical room from Market floor
 New electrical service installed in new
basement
 Each stand holder panel is individually metered
 109 electrical panels located throughout Market
 All distribution is located below slab to minimize
“clutter” of distribution systems
 Electrical savings of 15% - 30%, with seasonal
variation

24. Plumbing System Replacement
 New systems are located to restore usable space
to the Market floor where possible
 Systems are designed to blend with the historic
character of the building

 Maintain an operational market on this site
 Maintain an operational market throughout
construction
 Provide access to water and electricity at all
stand locations
 Provide opportunities for branding and signage
 Improve customer experience
 Manage future costs

29. Project Pre - Planning
 CMT rented adjacent vacant café space for use as stand
holder restrooms and break rooms
 Vacant market stands were retained prior to the project for
use as relocation space
 Underutilized locations on the market floor were used for
temporary locations for displaced stands
 Extensive 2-prong communication program

30. Phasing and Execution
 Designed to be completed in 13 phases to maintain market operations
 3 week phases

31. Phasing and Execution
 Design of all trenching and systems accommodate phased installation
 Existing systems remained operational until new systems were complete
 Phased areas were isolated to control dust and dirt
 Construction activities were planned and
executed to accommodate ongoing market
activities

32. Phasing and Execution
 Market remained open to customers during all regularly scheduled days
 No stand holders were forced to close at any time during the project

33. What’s Next?
